Security Vulnerabilities - CVEs Published In February 2025
In the Linux kernel, the following vulnerability has been resolved:
mlxsw: spectrum: Guard against invalid local ports
When processing events generated by the device's firmware, the driver
protects itself from events reported for non-existent local ports, but
not for the CPU port (local port 0), which exists, but does not have all
the fields as any local port.
This can result in a NULL pointer dereference when trying access
'struct mlxsw_sp_port' fields which are not initialized for CPU port.
Commit 63b08b1f6834 ("mlxsw: spectrum: Protect driver from buggy firmware")
already handled such issue by bailing early when processing a PUDE event
reported for the CPU port.
Generalize the approach by moving the check to a common function and
making use of it in all relevant places.

In the Linux kernel, the following vulnerability has been resolved:
drm/amd/display: Fix memory leak
[why]
Resource release is needed on the error handling path
to prevent memory leak.
[how]
Fix this by adding kfree on the error handling path.

In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: hci_sync: Fix queuing commands when HCI_UNREGISTER is set
hci_cmd_sync_queue shall return an error if HCI_UNREGISTER flag has
been set as that means hci_unregister_dev has been called so it will
likely cause a uaf after the timeout as the hdev will be freed.

In the Linux kernel, the following vulnerability has been resolved:
drm/amd/amdgpu/amdgpu_cs: fix refcount leak of a dma_fence obj
This issue takes place in an error path in
amdgpu_cs_fence_to_handle_ioctl(). When `info->in.what` falls into
default case, the function simply returns -EINVAL, forgetting to
decrement the reference count of a dma_fence obj, which is bumped
earlier by amdgpu_cs_get_fence(). This may result in reference count
leaks.
Fix it by decreasing the refcount of specific object before returning
the error code.

In the Linux kernel, the following vulnerability has been resolved:
scsi: pm8001: Fix memory leak in pm8001_chip_fw_flash_update_req()
In pm8001_chip_fw_flash_update_build(), if
pm8001_chip_fw_flash_update_build() fails, the struct fw_control_ex
allocated must be freed.

In the Linux kernel, the following vulnerability has been resolved:
ath11k: Fix frames flush failure caused by deadlock
We are seeing below warnings:
kernel: [25393.301506] ath11k_pci 0000:01:00.0: failed to flush mgmt transmit queue 0
kernel: [25398.421509] ath11k_pci 0000:01:00.0: failed to flush mgmt transmit queue 0
kernel: [25398.421831] ath11k_pci 0000:01:00.0: dropping mgmt frame for vdev 0, is_started 0
this means ath11k fails to flush mgmt. frames because wmi_mgmt_tx_work
has no chance to run in 5 seconds.
By setting /proc/sys/kernel/hung_task_timeout_secs to 20 and increasing
ATH11K_FLUSH_TIMEOUT to 50 we get below warnings:

In the Linux kernel, the following vulnerability has been resolved:
drm/sprd: fix potential NULL dereference
'drm' could be null in sprd_drm_shutdown, and drm_warn maybe dereference
it, remove this warning log.
v1 -> v2:
- Split checking platform_get_resource() return value to a separate patch
- Use dev_warn() instead of removing the warning log
